Secure key distribution is the fundamental problem in traditional symmetric key cryptography. Many techniques came into existence to safeguard key distribution. The core functionality of a key management technique is to share a secret key between two parties in secure and efficient fashion. This is the most important concern when cryptography is integrated with a communication network. Adversaries can exploit vulnerabilities in key management mechanism. Quantum key distribution is a promising technique that ensures unconditionally secure distribution of a bit string, a secret key, between two end points. Since quantum cannot be cloned or split, it can be used for providing fool proof mechanism for secure and efficient key management. This paper proposes a novel key management framework with underlying customized protocols to form a quantum trusted network that serve e-Governance applications in India. The custom protocols help to overcome the point-to-point limitation of quantum besides curbing security loopholes for reliable and provably secure communications. Quantum device provided by "Quantum in Cloud" of University of Bristol is used for the empirical study of the proposed framework.
This paper explores the exponential growth of equity derivatives market in India. Equity F&O segment on the nation's stock exchanges recorded a turnover 15 times of the cash market in 2014-15.The total turnover in equity derivatives market rose by 59.7 % when compared to 2013-14. This paper traces the growth and present status of India's equity derivatives market. It further attempts to infer reasons for this phenomenal growth from extant literature and secondary data sources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
